MSU Stereo To Multiview 3D Video Conversion - content creation technology for glasses-free 3D displays

Introduction

Now 3D visualization is a fast developing technology. Autostereoscopic glasses-free 3D monitors are already available. But video materials for them are still rare. Most of this video is rendered. 3D video creation is expensive and complicated task, because glasses-free 3D displays require several views of the same scene (usually 8-9 views). Stereo video capture is much easier. Stereo films become more and more popular. Our lab have developed stereo to multiview video conversion algorithm for glasses-free autostereoscopic 3D displays. This algorithm makes 3D video creation problem less complicated.

Stereo to multiview conversion

Work description

It is necessary to generate intermediate views to convert stereo to multiview intermediate.

We have developed conversion algorithm and processed several professionally captured stereo videos. We also researched 3D video capturing (more about MSU 3D Video Capture).

Intermediate views interpolation

Intermediate views generation doesn’t use depth map construction and semitransparent objects processing is correct. We also work on depth and disparity map generation. It can be used in monoscopic to 3D video conversion.

Our stereo video converting doesn’t need iterative processes and it is suite for stream processing. Real-time realization is possible. We also work on GPU version of conversion for more acceleration.

It is also possible to create multiview or stereo video from monoscopic sequences. We developed a conversion algorithm that uses only temporal and spatial frame information to generate 3D video: MSU Depth Map Generation and Stereo video creation.

How to view 3D video

To view 3D images you need autostereoscopic monitor and specialized player. Depending on how many views does your monitor support you should download 5-view or 9-view video. View order is also important. You should choose view order (from left to right OR from right to left) supported by your player.

5 view alignment: 9 view alignment:
5 view alignment. From left to right. 9 view alignment. From left to right. 9 view alignment. From right to left.
From left to right From left to right From right to left
9-view frame
9-view frame

Conversion output format can be also specified to be a sequence of numbered views or other appropriate way.
